REGULATOR FOR STEAM-PUMPS.

SPECIFICATION forming part of Letters Patent No. 250,076, dated November 29, 18 81.

Application filed May 9, 1881. (No model.)

To all whom it may concern Be it known that I, HENRY KESSLER, of San Francisco, in the county of San Francisco and State of California, have invented a new and useful Automatic Boiler- Regulator for Steam-Pumps, of which the following is a specification.

The object of my invention is toprovide a feed boiler-regulator for steam-pumps, so as to keep the water at all times to the desired height in the boiler and regulate the speed of the pump in an automatic manner. I attain this object by the mechanism illustrated in the accompanying drawing, which is avertical section, partly in elevation.

The metal casing A stands vertically,and is connected to the steam-boiler by means of the pipes K and L-the pipe L entering the boiler below the water-line, and the pipe K entering the boiler above the water-line, as shown-in which position the casing is held so as to bring the horizontal line B B to a level with the water-line of the boiler. The casingisalso divided horizontally at thelineB B, and a chamber, I, is formed therein, the two parts being connected and held together by bolts a a. In this chamber I place an air-tight float or globe, C, of suflicient capacity, when partly immersed in water, of sustaining the stem or rod D and valve E, the rod being connected to the valve by a nut, I). The balance-valve E is provided with V-shaped ports E, which are cut through it from theinside to the outside thereof. Leading into this valve is the steam-passage G, which connects with the steam-cylinder of the pump, and above the valve E is the pipe or passage H, which connects with the steamboiler at any point above the water-line.

Attached to the lower end of the casing is an exhaustor drain cock, M.

The object of the steam-passage which leads from the steam-chamber of the boiler and enters the chamber I through the medium of the pipe K, as shown, and the passage which leads from the boiler from below the water-line and enters the chamber I through the medium of the pipe L, is to keep the float C balanced, it being intended that the steam which is admitted from the boiler through the pipe K and the water from the boiler through the pipe L rises in the steam-boiler the float C, with balbi -1 ance-valve H, will descend and close the ports F of the valve, and thus diminish the steamsupply to the pump, which, in turn, diminishes the supplyof water to the steam-boiler, and so on inaregnlar, automatic manner. The pressure, being equal on the steam-pipe K and water-pipe L, will keep the float in position.

Should it be found desirable to provide the boiler with a greatersupply of water than that intended as the regular height or water-line, this may be accomplished by shutting off the water-supply to the chamber I by means of a cock, 0, connected to the supply-pipe L, and opening the drain cock M, which draws the water from the chamber I and causesthe valve E to descend, carrying the float C to its seat at the base of the chamber, which admits a full headvof steam through the passage G to the pump.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

In anautomatic boiler-regulator for steampumps, having a casing, A, and chamber I, the combination of the float C, provided with stcm D, and valve E, with the ports I', communicating with the steam and water passages G, H, K, and L, and drain cock M, all constructed,arranged,andoperatingsubstantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 21st day of April, 1881.
